Application filed May 29, 1919. Serial No. 300,705.

The invention has reference to a device for dispensing soap in the form of a pasty mass suchas is used by mechanics and other artisans, and the general object of the in vention is to provide a device of advantageous construction and arrangement adapted to dispense soap'in a semi-liquid state in measured quantities.

A more specific object of the invention is to provide a soap dispenser of the character indicated in which the soap container is capable of being readily detached when emptied and a new one filled with soap quickly secured in operative position.

A further object of the invention is to provide a soap dispenser in whichthe container for the soap becomes ruptured in use, which renders it incapable of use a second time by refilling. 1

In the drawings, Figure 1 is a top plan view of our improved soap dispenser. Fig. 2 is a fragmentary sectional view taken on line 22 of Fig. 1. Fig. 2 is an under side view of a soap cutter adapted to be secured to the dispenser. Fig. 3 is a fragmentary horizontal sectional view taken on line 3-3 of Fig. 2. Fig. 4 is a horizontal section taken on line 44 of Fig. 2. Fig. 5 is a view similar toFig, 2 but showing another form of soap container and plunger. Fig. 6 is a detached view of the container shown in Fig. 5' but in the form of a soap package. Fig. 7 is a transverse sectional view taken on line 7-7 of Fig. 5.

The dispenser comprises generically, a supporting bracket 8; a receptacle or container 9 or 9 detachably secured to the under side of the bracket 8 and having a tapered or conical discharge end or nozzle 10 or 10; a plunger 11 or 11 operable in the containers 9 or 9*; an operating stem 12 having a screw-threaded engagement with the plunger 11 or 11 and actuating mechanism for the stem operable by means of a handle 13. a

The bracket 8 comprises an upright fastening portion 8 and a horizontal portion 8 for supporting the soap container and the plunger operating mechanism. The 'container is made cylindrical in form and at its upper end is provided with an outwardly extending flange 14. To support the upper end of the container the bracket portion 8 is provided with a screw-threaded socket 15 in; its under side be of any preferred construction. 1t 13- shown as comprlsmg a shde 24 prowhich is thus formed part of the bracket which would normally form the bottom wall of said cavity is cut away so as to form an enlarged opening 18' in the bracket and this opening is closed by a separable plate 19 which is secured to the bracket as by means of screws 20. When the soap container is entered into the socket 15 in the bracket, the collar 16 serves to clamp the flange 14 against the under side of the plate 19.

In the construction shown in Fig. 2, the container 9 is preferably made of fiber board with metal securing rings at its opposite ends. Thus; the flange 14 at theupper end of the container, is formed on a metallic ring suitably secured to the outer periphery of the cont'ainerand at its lower end the container is provided with a screw-threaded ring 21 as ameans by which the lower discharge nozzle 10 of the containerj may be detachably secured thereto, said discharge nozzle being in this instance made for use with different containers and hence of a permanent character. Accordlngly, 1t is preferable to form it of metal, and at its upper end it is provided with an annular portion 22 internally threaded so that the nozzle may be secured in holding engagement with the ring 21 on the lower end of the container.

By reason of the fact that the nozzle is "made taperedor' conical in form the soap will not discharge therethrou'gh except when the plunger is actuated in the'operation of the device; and in order that when a quantity of soap is discharged it may be conveniently removed for use, a slicing or cutting device may be removably fastened as by means of a set screw 23 upon the extreme lower endof the nozzle which for this purpose may be made annular in form as at 10 (Fig. 5). This device 23 may Herein vided with a circular opening 25 normally registering with the discharge outlet and having a depending finger-engaging portion 26 by mcansof which the slide can be moved against theaction of a spring 27 to out oh the soap which has been forced through the opening 25.

The plungr 11 maybe in the form of a flat disk of suitable construction and. has

fixed on one side a nut 28'which is made sectional in form so that it may be disen gaged from its threaded engagement with the stem 12. Thus, as shownin 4:,one of the sections is pivoted at one end as at 28% and the other section carries a pivoted latch member 29 carryinga pin 30 which is movable into holding engagement with a notch 31' formed in the. pivoted section of the nut. The onening in the disk portion of the plunger is made sufiicient-ly large to .enable the. plunger tobe slid longitudinally when the pivoted section of: the. nut is: in inoperative position.

The operating stem 12 extends vertically through theportion 8 of the supporting bracket 8, suitable, openings being provided therein and in the. plate 19 for this purpose, and the. lower portion 013 the stem depends into, the container. The actuating mechanism for the stem. is; operatively' associated with the upper end thereof and is partially enclosed; within the cavity 17 formed in the bracket. This mechanism may comprise. a toothed ratchet wheel 32 keyed onto the stem and-adaptedito be. engaged by a springpressed dog 33 carried by the operating handle 13. This handle has tormed on its inner end a cup shaped portionBtt swingable on the stem as an axis and having a tension spring 35 fixed thereto at one end, the other end 01 the spring being fixed to the bracket at 36 (Fig. The cup-shaped portion 34 of the hand-leis made of suflicient depth to neatly receive the ratchet wheel 32. It Will be understood that the cavity 17 and the bracket are cut away at oneside to accommodate the handle 13, the opposite ends 37 and 37? of the opening thus formed serving as stops to, limit the swinging movements of the handle 18.

Referring to Fig. 8, a movement of the handle 13 in a clockwise direction rotates the stem 12 and'thereby causes the plunger to movedownwardly. lVhen this moyement o he and e is reste by he top 7% a measuredquantity of soap has been forced through the discharge nozzle, whereupon, the handle being released, the spring 35 retracts into, position against the stop 37, the dog 33 escaping past the teeth on the ratchet wheel When the plunger has reah h le e e d o e sen nce the seetional nut 28 may be disengaged from the stern and the plunger slid back to its posii d a t ne r end t ea Ita ny time, it is desired to retract the plunger in the eentainer, this may be accomplished by rotating the, same ,and tothisend the upper end of the stem is squared andthe opening sufiiciently large to permit the insertion thereinto of the socketed end of a crank 38.

In the. form of the dispenser shownin Figs. 5 to 7, the container 9 is adaptedto be ruptured in the operationof forcing the soaptherefrom, thus rendering the containers used non-refillable. In this embodiment of theinvention the nozzle 10 is made integral with the container proper, the latter being preferably made of tin or the like. At 1ts upper. end the. container 9 isflanged as at l l which flange is adapted to be clamped. in the supporting bracket in the manner. above set forth. The means forrupturing the container are herein in the form of prongs or projections 39 carried by the plunger and adapted to pierce the walls of thecontainer in the operation of the plunger.

Herein the plunger. is shaped to conform to that of the interior of the discharge nozzle and the projections-are, formed on the bottom side of the plunger so that when the plunger approaches the bottom of the container, the. projections serve to. rupture it, as shown, in dottedlines in Fig. 5. The plunger may be constructed" in. any preferred; manner. Herein. it is made in the form of a hollow inverted cone with a central tubular stem 40 internally screw-threaded so as to operatively. engage with the operating stem.

In Fig. 6, the container is shown as a soap package. Thus it: is provided at its upper end with a cover &1 frictionally held in position in, a well known manner. Preferably the cover is cone shaped so as to form a, depression for the plunger in the soap which fills the upper portion of the container. To provide a bore for receiving the operating stem 1221 rod or core 42 is inserted into, the container, said rod having a head 43 on its lower end closing the discharge end oi. the container.

Whilewehave herein illustrated and described our invention with considerable particula-rity, it will be understood that the invention is not to be limited in the interpretationof the appended claims except as may be necessitated by the state of the prior art.
